Besides the private contractors (that may even get paid on a commission), I bet a lot fo the Fitness Club employees are spending time on ServeNation as well (possibly at very little extra cost - maybe a little OT).
As a restaurant we have a merchant account with our CC processor , it takes 2-3 days depending on the cc used, Amex,Mastercard or Visa. I do not know it this would apply to Servenation because a different % have to taken from the total sale and distributed so the processing time might be longer.JMO
